Sand-blasting cabinets?

Is it really easier & cheaper to make one of these by the time you buy all the accessories & supplies? I would like some more details on how you made yours. Money is tighter than usual but parts still need to be cleaned. Any help would be appreciated.

The plywood I recycled from the floor of my old shed and the 2x4 is something that was picked up from my mother in law who happens to have a basement full of useable wood from her hunband who died 2 years ago. The angle iron came from an old bed frame I picked up for free. The hinges for the lid are recycled from an old door. Lexan I have,a buddy gave me a couple of pieces a while back in a trade. The glue I already had from installing my new shop door as is the silicon. I had 8 or so carriage bolts,so I bought a bag of 50 at the hardware store for $3.50. A siphon blaster I had,anyone can pick one up from Walmart for less than $15. I do have plans and material for building a pressurized blaster and only had to buy hose plus the nozzle. All the air line and fittings I need I will recycle from the galvanized plumbing I am slowly replacing in my house.Gloves are well used welding mits and the sleeves will be made from air bed rubber. The dust removal motor is the motor from the same air bed. I have a light fixture for a bulb kicking around and I'll use a rough service bulb in it so it will last. I even have used trunk seals from a big G.M I saved in case theres too much leakage around the lid.

It's all about reusing stuff you have or scrounging it up.My father in law was huge on stripping away and keeping useable stuff when doing reno's and Im much the same but tend to keep car parts more than house stuff,lol..

I plan on adding wheels from an old lawnmower so it's easy to move and clean up around it.

I did end up buying a new stapler as I misplaced my old one.

Im sure I'll have less than $20 tied into it when done. The blaster I'll need to spend about $100 but I'll end up with 2 tanks.
